How to use the Percentage Calculator
Calculate a percentage of a value, one value as a percentage of another, or percentage change.
- 1 Choose the panel that matches your question.
- 2 Enter X and Y, or the From and To values.
- 3 Read the result and verify that the baseline is the one you intended.
Example and practical tips
A change from 80 to 100 is a 25% increase, while 20% of 100 is 20.
Frequently asked questions
Are percentage change and percentage points the same?
No. A rate moving from 10% to 15% increases by five percentage points but by 50% relative to the original rate.
What if the baseline is zero?
A relative percentage using zero as the denominator is undefined. Choose another way to describe that change.
